IMPROVEMENT IN DENTAL FORCEPS.-

Specification forming part of Letters Patent No. 122,012, dated December19, 1871.

To all whom it may concern:

Be it known that I, LEONARD GEORGE HAs- KINS, of Newport, in the countyof Herkimer and State of New York, have invented an Improvement inReversible Forceps; and I do hereby declare that the following, taken inconnection with the drawing which accompanies and forms part of thisspecification, is a description of my invention sufficient to enablethose skilled in the art to practice it.

This invention relates to a new and useful improv ement in dentalforceps; and consists mainly in reversible jaws, constructed andarranged to operate in combination with the handles, as hereinaftershown and described.

In the accompanying drawing, Figure 1 is a view of my reversible forcepscomplete. Fig. 2 represents the jaws detached from the handle. Fig. 3 isa longitudinal section of Fig. 1 taken on the line oo r. Fig. 4 is asection of one ofthe handles, showing the mode of securing the jawtherein.

Similar letters of reference indicate corresponding parts.

A and B are the handles; C and D are the jaws. Each jaw has a beak, E,at each end, and they are fitted together by halving, as seen in Figs. 2and 3, having a central hole, f, for the pivotbolt g, by means of whichthey are fastened to the handles. lb is a plate on the end of eachhandle, forming, with the end t, a right angle in cross-section. Thehandles being reversed, the

jaws are inclosed within the quadrangle thus formed, and the four partsare held together by the pivot-bolt g, as seen in Fig. 3. In order toopen and close the jaws when they are thus connected with the handleseach plate h has a pin, J. lo represents two holes in each of the jaws,which receive the pins J, as seen in Fig. 3. The jaws are operated byIneans of these pins, whichever pair of beaks may be in use.

By making thev jaws thus detachable and reversible a single pair may beadapted to most dental purposes; but a variety of jaws suited forall thepurposes for which dental forceps are used may be ltted and madereversible in a single pair of handles.

I do not limit or confine myself to the precise form or arrangement ofthe parts described, as they may be varied in many wayswithout'departing from my invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The reversible jaws O and D, in combination with thehandles A and B, substantially as and for the purposes described.

2. In a forceps with reversible or detachable jaws. the pins J and holesk, substantially as and for the purposes described.

3. The jaws O and D, with the pivot-hole f therein, halved together, asshown and described, for the purposes set forth.

4. The pivot-bolt g, in combination with thejaws O and D.

5. The plates h, pins J, and holes j, in combination with the handles Aand B, substantially as and for the purposes described.
